This invention relatesr to easement windows and doors. of the sliding-hinge type. The swinging sashes of such windows areeasier tov operate and to clean on the outer sidethan the ordinary sliding sash, but their general adoption has been hindered by the fact that such windows heretofore could not be made weathertight without.

troublesome and costly expedients., w i, An object of the present invention is toprovide mainly or wholly concealed when the sash is closed, according to -which the window joints are substantially sea-led .against the passage of .airv and moisture. AFurther objects are to Afacilitate removal of .the sash, to provide for drainage of water from the lower guide and to furnishan improved stop device.

.3,5 The sash and frame are here shown as adapted for wooden construction, but theinvention also applies to metal windows The sash could swing oneither a vertical or a horizontal axis, and is shown in the former way. The side toward which the sash swings in its opening movement is considered the front, which is generally the outer side of the building. The window is here illustrated as a panel or section in a larger window whose marginal portions can be xed inthe build- 45 ing WalLbut its frame could obviously` be. xed

50 angupperhorizontal or headjamb 13 anda lower horizontal jamb or sill member 414. The latter in the case of a wooden frame is preferably made as a separate member overlying and screwed to the main sill member 15 between the side jambs,

- and adapted to be shortened inl depth by planing a. simple and inexpensive mounting, whichisv oli? its under side to avoid sticking of the sash due to swelling or distortion'of parts after the window has beeninstalled. `16 is the sash opening defined by the frame V10. 17 and 18 are vertical and horizontal ange strips to whose front sides are glued felt packing'strips 19 as shown in Figs. 1 and 3 tofform ai rear stop for thesash and provide arweathertight joint `between the frame and the sash on.the .innerside of said sash when the latter is closed.: x

V--The upper and lower jambs-13 and 14 are each formed with a rectangular groove 20 (Fig. 3) located toward the-front side of said member and extending from end to end pthereof. In each grooveYA iscemented a channeled metal Vguide vor track21 for the slidable hingeV member of the sash and aY solid metal bar 22-mounted in align. ment .withsaid track and slightly spacedvtherefrom:v to provide track drainage, said bar at one endacting as a stop forthe sliding hinge and at 75 the other vend as a pivotal support for the sash link.` Said V.track andbar are further secured by screws in their groove. I Between the inner ends of the track andrbar is an opening 23, wedgeshaped in plan,.horizontally open on the front sidel and partlyformed in the wood of the lower sillyor jamb member ,14 by cutting away the latter with `an outwardly and downwardly-sloping bottom, said bottom and the rear sideof the opening being facedrwith a putty-like cement lining 24 (Fig. 3) tov seal the crevices. This opening 23 provides a channelor outlet tothe front of the sill `for water. which may collect Yin `the channeled` track 21 and which would tend-,to cause corrosion-if allowed to remain, said channel Ybeing upwardly open as shown, to permit easy removal of any obstructing m-atter.v y

vv25 is the window sash to whose upper and lower edgesare screwed respective plates 26 each having a-permanent pivotal connection at 27 with a at guiding link-bar 28 to whose other end is xed apivot pin .29 removably mounted in a hole 30 in the bar` 22 to facilitate removal of the sash from its frame,A Each ofthe link bars 28 is -al spring structureV slightlyY vbowed or bent 'toward the jamb 13 `or 14 withvwhich it engages to furnish a tension florjre'taining the pivot pins 2.9 intheir holesin the bars 22 when the sash is swung open. l Onelend of each ofthe 'plates26 is' formed with :a: hinge member 31 projecting 'beyond the vertical edge face of the sash 25, the lower and upper hinge members being provided'with respective pivots or hinge pintles 32 and 33 which are thereby fxe'dly secured upon and spaced `oroifset ture in order that the opened sash may auto-. matically blow shut by excessive wind pressure in case of a storm. In the full-open position of the sash, one leg of the shoe 34 is stopped by abut-1A ting against the inner endhof the barh22 before the sash has reached a position alfright" angles to the frame, in order to make it easientoclosej said sash. While a similar spring shoe could be provided in connectionwith theupper hinge member 31, it is preferredtoomit it in that case and make the upper hinge `pin 330i sufficient-diameter for direct guiding engagement with. the correspondingtrack21.v v 1, a

When the sash is closed, its projectingvhinge members 31, the pintles 32 and aportion ofthe spring shoe 34 are receivedinrespective horizontal pockets or recesses'35 formed in the jamb l1 at the upper and lower corners voflthe sash opening and the corresponding vends. of the tracks 21 are also extended' into ltheseY pockets.

Thedescribed offset hinge construction permits the use of a front sealing lip or flange 36 on all four edges of the sash tooverlap the front faceof the window` frame 10 and supplement the seal formed between the rear side ofthe sash and the felt-packed frame flanges 17--and.18,^and thus to provide substantially weathertight window joints when the sash is closed'. Fig. 1- shows how the offsetting of the hinge axis avoids interference between the sealing flange 36 and the horizontal frame jambs when the window is open. It will be evident that when the window is' shut' the described sash mountings, being located within'the thickness of the frame, are covered and substantially concealed by the sash, and when saidfsash is open, no portion of its body projects within the ,p window opening. In Fig. 1, a partly-closed position of the sash and 4link is indicated in broken lines. i Fig. 4 illustrates how the sash' can-be removed from its frame without unscrewing any" parts of the mounting from either frame or sash'ashas been required in prior structures of this class'.l

The sash is first swung open, the link pivots 29 are then removed from their bearing holes in the bars 22 by springing the links 28, said links are swung forwardly on vthe-sash to clear 'the frame and the sash' is then tilted in a direction parallel with the plane of the'window opening yto move its upper end toward the jamb 11 until hinge pin 33 comes out of the upper track 21 the spring shoe 34 at the same time beingtilted upwardly in the lower` track, whereupon the upper end ofthe sash can be swung outwardly andthe sash lifted to clear thelower hinge pingfromthe spring shoe. Thevsash is now free from the frame. and

. canbe turned and carriedI in through the window Y opening. This removalfcan be performed by an operator on the inside. s y. v

Fig. 5 representsa modification whereinjthe supplementary.'sealing'at the hinged edge of the sash is effected by means of ai, tongue or ridge 37 on the rear'vertical edge corner of the sash projecting laterally into a complemental groove 38 in the jamb or stile 11 when the sash is closed, the other three edges of the sash having front sealing lips or flanges 36 overlapping the frame as in the preceding embodiment. This construction is particularly adapted for a relatively-narrow stile because the absence of the front sealing lip on the hinged edge permits the amount of offset of the pivot 32y from said edge to bev reduced by an amount corresponding to the widthof 'said front .sealing lip.

In the modification shown in Figs. 6 and '7,

v'zeach of the plates 26 attached to the horizontal edgefaces of the sash 25, which is here represented "in broken lines, is formed with an outwardly-curved projection 31a constituting a hinge member and permanently connected by a pivot pin 39 vwith a complemental curved hinge mem- ,ber 4 0 l,formed on a sliding shoe 41. The top plate of this shoe overlies the track 21, and to a fin on its under side are attached a pair of spring friction plates 42 running inthe channel of the track. The kaxis of the'hinge pin 39 in this case could coincide with the -rear corner of the sealingflange 36 on the sash, but. to. provide'some tolerance affording suilicient flange clearance at all times, said axis vis preferably spaced a slight distance laterally from the edge of the sealing flange as indicated in Fig. 6.Y Pockets 43, open both'laterally toward the sash openingand to-the front of the frame, are formed inthe stile'or jamb 11 to accommodate these hinges when the sash is closed, and each of said pockets may, if desired, be covered by a detachable metal cap 44. In this modification, vall parts of the vsash mounting are substantially.,covered` or-concealed by the sash in its closed position except for-a forwardly-proyjecting part ofeach hinge, which may be substantiallylconcealed by the cap 44 as described.

5 I claim: Y v Y 1. In window construction, the combination of a window frame having channel trackson opposite members thereof, a swinging sash having pivots slidable on said tracks and freely separable from the latter when the pivot axis is tilted with the sash in an open position, and a spring slide in one ofsaid tracks, engaging the corresponding` pivot and adapted to tilt with the latter and emerge from the track in the course of such separation.

""2. In window construction, the combination of av frame having a sash opening, tracks on said frame, anda sash having `a mounting in said opening including slidable pivot connections between the tracks and sashyand spring link connections tending to a bowed shape pivoted to the sash and frame and normally retained in connected relation by the bowing tendency of the links, all of said connectionsbeing freely separable'when the sash is open topermit the removal Vof the latter withoutdisconnecting members of the mounting from the frame or sash.

'Y 3. A window frame having a sash opening" and provided on opposite' sides of said opening with guideways in the planeof the frame which at one end extend'inward intothe sideA members of the frame, thus providing'pivot receiving recesses; and a swinging sashv having hinge connections iso atthe side of the-sash which is ne'xttothe side and move intol thejrecesses when thesaShis closed;

hinge connections at the side of the sash which has the overlap, such connections rbeing located in the plane of the sash rigid therewith projecting out past its edge and provided at their ends with pivots which ride in the guideways and move into the recesses when the sash is closed.
